研究兴趣和材料体系：
低维轻元素量子材料的可控制备和性质研究
不同于其三维构型，二维材料“所有原子都暴露在表面”使得可以Atom-by-Atom精准解析结构，在二维空间中揭示原子尺度上的新型构效关系也成为可能。通过bottom-up的精准生长控制和top-down的人工堆叠制造，课题组的研究兴趣聚焦在轻元素量子材料及其异质结构，探索其本征的电、光、热、磁性质、调控手段和潜在应用。诚挚欢迎喜欢“Do Something New, Do Something Different”的博士后、研究生和本科生加入我们。
目前关注的体系包括（不限于）：
1）二维体系中的同位素效应
2）新型二维轻元素量子材料
3）轻元素无序材料
